Correct, multiselct, and patching is done with point/click, and a few keystrokes. Sometimes human error can occur, and the multiselect or patch is not released or the wrong ones added etc... Also, a few agencies have multigroup/multiselect/patches auto on a tone out. Key up an tone out, and it auto hits everything you preselected in programing. There are also times where "rebroadcast" is used... Such as an FD tone out being "rebroadcast" over an PD dispatch freq/tg for smaller agencies... While most larger agencies PD dispatcher/controller will just announce that FD is being dispatched to blah blah yadda yadda to keep the channel as free as possible. Some won't announce anything unless an officer asks "Hey, I just saw FD running code in my sector, whats up?"
